cation Serial No. 236,010, filed December 8,

The object of the present invention is -to provide an improved spring mounting for the irons.

Another object of my invention is to improve the structural parts of the rotating support.

The features of the invention are more fully setforth inthe description'of the accompanying drawings, forming a part of this is a section on line w, w, Fig. 2.

In this device the rotary support is specifically a hub l having the/bore 2, to receive the shaft to which the hub is fixed. Preferably, though not essentially, the hubis provided with, the raised end portions 3. The peripheries of these end portions 3 are milled out to 'forni slots parallel With the axis. One

of tlieseslots, say, 4 is' open from end to end,

While its opposing` lslot 5 on the opposite raised end is closed. These open and closed slots are alternately dis osed around the pe.- ripheriesof these raise ends of the' hubs 3. In the open end slot 4 is seated oneend of a supporting hair 6, being secured thereto lo'ya screw 7 passing loosely through the said bar 6 to allow a slight amount of play of the bar.

at this its attached end. The apposite or yielding end of the bar 6 extends into vthe closed slot i The raised portion 3 ofthe hubA are also provided with a series of radial orifices 8 :Within which is placed a series of coiled springs Q, projecting radially from said oriiices. upper ends of thefooiled springs will lie under and support the yielding ends of the bar 6. Upon the free ends of these bars 6 are sc eured the oppositely inclined irons 10,' sub- `Speeiicatipn of Letters Patent.

istantially the same as inthe device of my said prior application, and which need not be further described.

11 represents collars' having `Iianges 12 ,forming guards-over the, outer ends of the irons 10; These collars arefrictionally driven over the .ends of the hub seating upon the raisedportions 3.

It will be understood that the purpose of this device is to form heel seats. of shoes andv perform other finishing Work for the lasting of a shoe, and 'that the shoe is presented to the irons While the hub is being rapidly rotated. It is desirable that these irons shall be independently yielding and that the spring niountings shall be strong and durable.

My invention fully realizes this desideratum and therefore adds to the efficiency of the device.

Having described my invention, I claim 1. In a heel seat forming device, a huh, a series of irons and supporting bars pivot-ally attached to the hub, and lcoil springs supporting the free ends of the bars, substantially' as described.

2. In a device of the class described, a hub, a series of bars alternately attached at opposite ends to the hub, springs mounted between the hubs andthe freeends of the bars, and irons attached tosaid. bars, substantially as described. a

3. In a device of the class described, a hub, a series of bars alternately attached at eppoi site ends of the hub, the hub being provided With a series of radial orifices adjacent to the free end of said bars, coil springs Within said orifices upon the upper ends of which the free .ends of said bars engage, and irons secured to the said bars, substantially as described.

4., In a device of the class described., a hub having raised portions ateach end the peri heries of `which are provided with a series of? axially extended. slots, a series of bars alternately seated in said slots, with their free ends extending into the intermediately alternating slots, the hub being provided with a .se--

ries of radial orifices under the free .ends of the bars, coil springs Within said orifices upon the upper ends of which the free ends of said' bars engage, and irons secured to said bars, substantially as described.

5. In a device of the class described, a hub having raised portions at each end the peripheries of which are provided with a series TOO of axially'extended slots, a series of bars alhub, having gL-:ird enges overhanging the 'm ternately seated in said slots, with their free ends extending into the intermediately lalteri naming slots, the hub being provided with 5L series of radial orifices under the free ends of the bars, coil springs within said orifices upon the upper ends of which the free ends of said bars engage, irons secured to sziid bars, and Collars seated upon the said raised ends of the my hand.

outer'ends of sand irons, substantially as described.
